The dillema.
Ammo costs: 45 ACP FMJ is cheaper than 9mm JHP.
The time-honored old American .45 ACP fodder has less of a chance of running out of stock on shelves. 9mm JHP is expensive and has trouble staying on shelves.
Sometimes it makes sense to choose a defensive handgun based on ammo availabilty and prices.
Bigger, heavier .45 ACP gun, maybe more kick but cheaper ammo, round per round.
The 21 is a bit longer and heavier. Which recoils more, the heavier .45 ACP or the lighter 9 mm Glock pistol?
Cheaper FMJ bullets are fine for defense with .45 ACP because of the wide frontal area. The smaller 9mm caliber needs expensive jacketed-hollowpoint bullets to give "45-like" frontal area stopping power.
